After watching an area of disturbed weather for several days, the National Hurricane Center has determined that Subtropical Storm Alberto has formed in the Gulf of Mexico. The storm, currently near the Yucatan Peninsula, is forecast to crawl northward throughout the holiday weekend.

The impact: The storm is eventually likely to come ashore somewhere between Louisiana and the Florida Panhandle early next week — possibly as soon as Memorial Day. The storm's biggest threat will not be its winds, but rather, its rains.
